Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar grid construction, and in particular relates to a small-diameter steel bar quick hook bending tool. Background Art

[0002] In construction projects, there are many types of steel mesh. In most cases, stirrups and tie bars are processed and formed in the steel processing shed and then transported to the construction site for use. However, due to the presence of complex node beams, large-section beam stirrups and slab tie bars and other structural steel bars at the construction site, if these stirrups and tie bars are formed once and then assembled at the construction site, it will increase the difficulty of on-site installation of the stirrups and tie bars. Therefore, it is necessary to bend and shape them on site to complete the assembly of the steel mesh.

[0003] Publication No. CN214078983U discloses a steel bar hook bending correction tool, comprising a main rod, a first claw rod is welded and fixed at the end face position of one end of the main rod, the first claw rod and the main rod are connected in a T-shape, a second claw rod and a third claw rod are welded and fixed to the side wall of the main rod, the second claw rod and the third claw rod are symmetrically arranged with the main rod as the central axis, the second claw rod and the third claw rod are vertically connected to the main rod, the second claw rod and the first claw rod form a first correction jaw, and the third claw rod and the first claw rod form a second correction jaw. Although the tool is used for manual bending of steel bar anchor hooks and correction of steel bar roots, the first claw rod, the second claw rod and the third claw rod are all rod-shaped structures that are parallel and spaced from each other. When the root of the steel bar is corrected, the force point forms a crowbar effect at the lower end of the first claw rod and the second claw rod or the third claw rod to achieve straightening of the root of the steel bar. When this type of tool is used to bend the stirrups and tie bars of the steel mesh, since the stirrups and tie bars need to be bent along the outer circumference of the main bars and are wrapped around the main bars to form a shape, this type of bending correction tool is not suitable for temporary processing of stirrups and tie bars of the steel mesh on site.

[0017] The following will be combined with the accompanying drawings to describe the embodiments of the present invention in detail, so as to more clearly understand the purpose, characteristics and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0018] like Figure 1 , Figure 2 As shown. The utility model provides a small diameter steel bar quick hook bending tool, including a hand-held grip 1, one end of the grip 1 is provided with a rotating part 2, the rotating part 2 has at least one concave groove 202 for rotating and embedding the main steel bar and rotating around the main steel bar. One side of the rotating part 2 is externally connected to one end of the grip 1, and the other side of the rotating part 2 is provided with a notch 201 opposite to the end of the grip 1 and for embedding the small diameter steel bar, the notch 201 passes through the concave groove 202 to the outer peripheral surface of the rotating part 2, and one end of the notch 201 passes through one side of the rotating part 2, and the other end extends to the edge of the other side of the rotating part 2.

[0019] Specifically, the grip 1 is a straight rod, and the front end of the grip 1 is welded with the rotating part 2, and the axial direction of the rotating part 2 is vertically connected to the grip 1. The rear end of the grip 1 is used for hand holding. The concave groove 202 is arranged along the axial direction of the rotating part 2, and the notch 201 is arranged along the radial direction of the rotating part 2 to penetrate the rotating part 2. The concave groove 202 is nested on the main steel bar and can rotate around the main steel bar. The grip 1 is rotated and the hand-held force is applied to the rotating part 2 to make the rotating part rotate around the main steel bar. Then, after the notch 201 is rotated, the small diameter steel bar can be bent along the main steel bar, and the bent small diameter steel bar is placed around the radial periphery of the main steel bar.

[0020] Furthermore, the cross section of the rotating portion 2 is a C-shaped structure, and at this time, the inner cross section of the concave groove 202 is also a C-shaped structure.

[0021] As a preferred embodiment, the rotating part 2 is made by bending a steel plate. Before bending, a notch 201 is firstly formed on the steel plate, one end of the notch 201 passes through one side of the steel plate, and the other side extends to the edge of the other end of the steel plate, and then the rotating part 2 is formed after bending, so that the inner cross section of the concave groove 202 is a C-shaped structure, and the notch 201 after bending is in a C-shaped bending shape. The extension direction of the notch 201 is perpendicular to the main steel bar.

[0022] Of course, as a preference, the cross section of the rotating part 2 can also be a semicircular structure. In this case, the rotating part 2 is made of a steel cylinder with half of its axial section cut off to form a snap ring sleeve, so that the cross section of the concave groove 202 is arc-shaped. The notch 201 passes through the inner and outer circumferences of the snap ring sleeve, and one end of the notch 201 passes through the cut surface, and the other end extends to the edge of the other cut surface.

[0023] Furthermore, in order to facilitate the embedding of the small diameter steel bar, the notch 201 is a U-shaped structure. The open end of the U-shaped structure passes through one side of the rotating part 2 opposite to the grip 1, and the closed end of the U-shaped structure extends to the inner edge of the other side of the rotating part 2 connected to the grip 1. The opening width of the U-shaped structure is slightly larger than the outer diameter of the small diameter steel bar.

[0024] As a preferred embodiment, the groove 201 can also be a V-shaped groove, the open end of the V-shaped groove passes through one side of the rotating part 2 opposite to the handle 1, and the closed end of the V-shaped groove extends to the inner edge of the other side of the rotating part 2 connected to the handle 1. The closed end of the V-shaped groove has a semicircular through hole to facilitate the embedding of small diameter steel bars. The semicircular through hole is tangent to the two edges of the V-shaped groove, which facilitates the small diameter steel bars to enter the through hole from the open end of the V-shaped groove.

[0025] Furthermore, the notch 201 includes a first opening and a second opening, the width of the first opening is greater than the width of the second opening, the first opening is located on one side of the bending head, the second opening is located in the edge of the other side of the bending head, and the first opening and the second opening are connected to form a step shape. The stepped notch 201 is more convenient for embedding small diameter steel bars.

[0026] Of course, the connecting transition section between the first opening and the second opening preferably adopts an arc transition or a slope transition, in which case the small-diameter steel bar can be better embedded in the notch 201.

[0027] Furthermore, the second opening is a U-shaped structure, and the closed end of the U-shaped structure can also be a semicircle that matches the outer diameter of the small-diameter steel bar. The semicircle and the outer diameter of the small-diameter steel bar are clearance-matched.

[0028] As a preferred embodiment, when manufacturing the utility model, the rotating part 2 uses a steel plate with a width of 50mm, a length of 70mm, and a thickness of 5mm, and the gripping rod 1 uses a steel bar with a length of 300mm and a diameter of 14mm. After heating the steel plate, it is rolled into a C shape along the width direction, and then a hole is opened in the middle. The hole shape is an upper circular hole and a lower hole forming a notch 201. The circular hole has a diameter of 15mm, and the square hole size is 25mmX25mm, which is connected in a stepped shape. The formed steel plate and steel bar are welded, first spot welding and then cover welding to form a small diameter steel bar quick hook bending tool.

[0029] When the utility model is in use, the rotating part 2 rotates to embed the main steel bar, the notch 201 embeds the small diameter steel bar, and the hand-held handle 1 is rotated to bend the small diameter steel bar along the main steel bar, so that the small diameter steel bar is placed around the outer periphery of the main steel bar at 90 degrees.
